Effect of BJT's parasitics on computing cells for analog decoders
Résumé
This paper analyses the effect of inherent bipolar transistor parasitic elements over the computing nodes performance used in BJT analog decoders. It is shown that these undesirable effects significantly degrade, up to 85%, the conversion of Log-Likelihood Ratios into probabilities. This can lead to a wrong decoding outcome when complex computing nodes are designed. Simulation results are shown for a 0.25-µm BiCMOS process from NXP.
